Question

The energies of orbitals of h atom are in the order

Answer 1

In the hydrogen atom the energy of the electron depends only on the value of the principle quantum number n as shown by the solution to the Schrodinger Wave Equation and experimentally by the emission spectrum. The order ofenergies is 1s<2s = 2p<3s=3p=3d<4s=4p=4d=4f<5s=5p=5d=5f .
